Full textThe objective of this work is to study the effect of desiccation cracks on the thermo-hydro-mechanical behavior of clayey soils.The study includes an experimental study to characterize the influence of cracks on the drying process of clay samples and a numerical study in order to present the impact of cracks on the soil-atmosphere interaction.In the first phase of this study, an experimental work performed in the laboratory to characterize the influence of cracks on drying soil was conducted. Drying tests were conducted on samples of intact and cracked soil where the evolution of the water content and cracking due to drying were monitored. In the second phase of this study, the influence of cracks on the thermo-hydro-mechanical behaviour of clayey soil is presented. A two-dimensional numerical model of soil-atmosphere interaction has been developed considering the presence of cracks. The model takes into account the thermo- fluid coupling of an unsaturated clay soil.The model is used to simulate the evolution of evaporation during the drying process. It shows the impact of cracks on the suction development and water content evolution as well as the air entry value. This study also proposes a simple approach to the consideration of cracks in the soil-atmosphere interaction. In the last part of this work, the influence of cracks on the mechanical behaviour of fine soils is presented and discussed

Full textThe thesis aims to study the phenomenon of drought using a numerical modelling of interaction soil-atmosphere-structure and analyse the impact of drought on the structures. It has three parts: The first part includes a summary of work done on the drought, especially on transfer of mass and heat in unsaturated soils. The models proposed for coupling soil-atmosphere are presented. We also present the methodology determining the parameters involved in the transfer equations and soil-atmosphere coupling. The second part concerns the modelling of transfer of mass and heat in unsaturated soils by taking into account the soil-exchange atmosphere. We describe also the implementation of this model in finite element code (ESNA-LML) and the validation of this code. The chapter concludes with a study of soil-atmosphere exchange in the vicinity of structure and influence of soil characteristics and climatic conditions on the suction induced in the soil. The third part studies the influence of drought on the soil-structure interaction. The analysis is performed using a decoupled approach. Initially, the suction induced by the drought is determined by solving the transfer of mass and heat in soil taking into account the coupling soil- atmosphere. Then, a program of finite element (ESNA-LML) is used to analyse the mechanical response of soil-structure

Full textCrop Nitrogen Nutrition Status (NNS) relates the amount of nitrogen in plants in relation to needs for instantaneous growth. It is known that water deficit diminishes NNS through a series of processes belonging to plant nitrogen metabolism and soil nitrogen cycle. The NNS results from the balance between demand, defined by crop growth and the nitrogen that is available for plant uptake. The effect of water deficit on crop growth is well known. The effect on N uptake is caused by a) the soil water status that determines diffusive and convective flows of nitrogen, which are the responsible of transport of nitrogen to the roots and b) the plant water status that determines the needs of nitrogen for growth. Two experiments were made during summer 2003 and 2004 on tall fescue and Italian ryegrass, species with a contrasted growth system, which also enabled us to study the influence of root distribution in soil on the effect of water deficit on NNS. Measurements of the nitrogen nutrition index enabled us to follow the variations of NNS closely. Immediate responses of NNS to any change in system water status were measured, involving a variation in nitrogen flow to roots, mainly transpiration-dependant convective flow. To analyse a possible direct effect of plant and/or soil water status on N uptake, experiments in a split-root system and controlled environment were made. Results showed that independently of water effects on C fluxes, there was a direct effect, which was variable between grass species, and that might be related to a nitrogen accumulation in roots

Full textIn the context of anticipated climate change, increasingly intense and frequent episodes of drought will affect water availability for boreal tree species, prompting tree breeders to consider adaptation to water stress as a priority. We used a 19-year-old comparative test of white spruce (Picea glauca [Moench] Voss) polycross progeny established on two sites affected by drought episodes to compare the genetic control and the potential for improvement of drought response with those of more conventional growth traits. To do this, we used genomic selection (GS) based on genomic profiles and traditional selection based on pedigree information only (PS). The genetic control for drought-response traits was somewhat weaker than for growth traits, but with comparable estimated genetic gains, which makes it possible to consider the use of GS at an early age. The accuracy of predicted breeding values for drought response traits was only slightly lower than that for growth traits. We observed opposite correlations on the two sites studied between water stress resistance traits and tree radial growth, likely because the water stress episodes occurred at different times during the growth season between sites. However, some selection scenarios made it possible to improve all traits while sacrificing very little on height gain, which is the priority trait targeted for this species in Quebec. Our results suggest that integrating drought response into white spruce breeding programs would require only a slight sacrifice in height growth, but that the accuracy of predictions obtained by the genomic or the conventional approach is negatively affected by the lower numbers of trees in site-specific analyses when the water stress episodes are different from site to site.
Nasser, Thierry Tarek. "Evaluation et impact de la sécheresse sur une région agricole : Cas de la plaine irriguée de la Beqaa." Thesis, Orléans, 2019. http://www.theses.fr/2019ORLE1169.
Full textThe interior plain of Beqaa is regarded as the bread basket of Lebanon. The drought is one of the major problems, whether of climatic origin or due to poor management of the resource. This work focuses on agricultural drought and the link with meteorological drought in the semi-arid region of the Beqaa plain. In order to follow the evolution of the intensity of agricultural drought, the methods of remote sensing was applied. An indicator of drought, Vegetation Health Index (VHI), was computed from a measurement of vegetation and temperature obtained using the MODIS satellite sensor, allowing us to determine the driest years. This method was applied in order to understand the variation of the drought intensity on the agricultural territory. The intensity of drought varied considerably in time and space. An exceptional year of drought was detected, with a quarter of the agricultural surface, including the agricultural zones privileged in irrigation, affected by a severe drought. Subsequently, there is a link between the calculated drought index (VHI) and the rainfall, but this does not appear directly on its intensity in the agricultural zone. In conclusion, the drought is an ongoing phenomenon in the plain of Beqaa, variable in intensity and which could worsen if combined with climate change

Full textPelargonium drought resistance was studied. P. X peltatum genotypes were the most tolerant whereas the aromatic genotypes and P. X domesticum were the most susceptible. Variability was found in P. X hortorum. The accumulation of sucrose and other sugars of higher molecular weight characterized the tolerant genotypes. Two transformation methods were set up to improve drought tolerance. From leaf discs 100% of P. Graveolens, P. X hortorum and P. Capitatum explants produced respectively 7. 3, 8. 3 and 11,4 rooted plants per explant 8 – within 12 weeks. Efficiency of Agrobacterium tumefaciens-mediated transformation, reached 146% P. X hortorum and 346% for P. Capitatum. Transformation was confirmed by GUS assay, PCR and Southern-blot analysis. From leaf protoplasts, 40% of calli were formed from which 83% gave 2. 6 rooted plants within 21 weeks. These transformation efficiency was 1. 5 % of electroporated protoplasts giving. Finally, a genetic construct harboring 1-SST gene, isolated from onion and coding for fructan biosynthesis was made using the Gateway technology. This plasmid is ready to use for improvement of drought resistance
